DPSS Laser Modules

Working Principle of DPSS Lasers

• Pumping Mechanism: DPSS lasers operate by using a semiconductor laser diode to pump a solid gain medium, such as Nd:YAG or Nd:YVO4. The diode emits light at a specific wavelength, which is absorbed by the gain medium, exciting its atoms to higher energy states.

• Laser Emission: The excited atoms in the gain medium then release their energy in the form of coherent light as they return to their ground state. This light is amplified through stimulated emission, producing a highly focused and stable laser beam. The process is highly efficient, resulting in superior beam quality and high output power.

Difference Comparison: DPSS Lasers & Diode Lasers

• Beam Quality and Stability: DPSS lasers generally offer superior beam quality and stability compared to diode lasers. The solid gain medium in DPSS lasers allows for lower beam divergence and higher coherence, making them ideal for precision applications such as scientific research and medical procedures.

• Power and Efficiency: While diode lasers are highly efficient and compact, DPSS lasers can achieve higher power levels with better beam characteristics. Diode lasers are often used in applications where size and efficiency are critical, whereas DPSS lasers are preferred for tasks requiring high power and precise beam control.
